Novel material taking cyanogen-containing silicone oil as continuous phase and used for magnetic fluid tire sealing

Abstract

The invention discloses a novel material taking cyanogen-containing silicone oil as a continuous phase and used for magnetic fluid tire sealing and belongs to the technical field of tires. The formula of the novel material is characterized by comprising the cyanogen-containing silicone oil, barium sulfate powder, nano-scale samarium cobalt magnet powder, nano-scale ferrite magnet powder, diethyl ethylene diamine, magnesium stearate, rosin amine, isoprene rubber granules and an acrylate adhesive. The novel material is mainly applied to a radial tire adopting a steel wire tire cord layer, doesn't affect the dynamic balance of wheels, can rapidly and automatically repair a notch with the diameter smaller than or equal to 10 mm, is not dried up, doesn't freeze and is high in reliability and stability and durable. After use, with rotation of the wheels, a circle of magnetic fluid is uniformly applied to the inner wall of the tire. The magnetic fluid can be stably and uniformly applied to the inner wall of the tire through the suction action of the steel wire tire cord in the tire, the dynamic balance of the wheels is not affected, and revolutionary improvement is really realized by comparison with the prior art.

Description

technical field [0001] The invention belongs to the technical field of tires, and relates to a new self-replenishing material applied to radial tire sealing, in particular to a new magnetic fluid tire sealing material containing cyanosilicone oil as a continuous phase. Background technique [0002] Automobiles and various motor vehicles have become one of the important symbols of modern civilization. During their use, tires are punctured by nails or sharp hard substances on the road surface to cause deflation, which often causes the vehicle to fail to operate normally. The earliest automatic tire sealant was applied in the US military wheeled vehicles in the 1920s and 1930s. The tires of military vehicles were filled with automatic tire sealant. It has a history of 80-90 years. The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic ...
